How to cast long to byte in Java

In this first solution, given a long value we just simply cast it to a byte value as the following example Java code.

ConvertLongToByteExample1.java 

public class ConvertLongToByteExample1 {
    public static void main(String... args) {
        long longValue = 99;

        // Cast long to byte
        byte byteValue = (byte)longValue;

        System.out.println("long value: " + longValue);
        System.out.println("byte value: " + byteValue);
    }
}
The output as below. 
long value: 99
byte value: 99

Using Long.byteValue() method

In this second solution, with a given Long object we can use the Long.byteValue() to return the byte value as the following Java code.

ConvertLongToByteExample2.java 

public class ConvertLongToByteExample2 {
    public static void main(String... args) {
        Long longValue = 120L;

        // Convert long to byte
        byte byteValue = longValue.byteValue();

        System.out.println("long value: " + longValue);
        System.out.println("byte value: " + byteValue);
    }
}
The output as below. 
long value: 120
byte value: 120
